WILLIAM HENRY STARKEY AND JAMES THOMAS STARKEY, OF MONCTON, CANADA.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 491,450, dated February7, 1893.

Application filed April 12, 1892. Serial No. 428,777. (No model.)

To aZZ whom it may concern:

Be it known that we, WILLIAM HENRY STARKEY and JAMES THOMAS STARKEY,mechanics, of the city of Moncton, in the county of Westmoreland, in theProvince of New Brunswick, in the Dominion of Canada, have invented anew and useful Improvement in Car-Couplers, of which the following is aspeci- I'ication.

Our invention relates to improvements in machines for the coupling anduncoupling of railway cars in a new and improved manner which can beapplied to all cars of whatever nature and we hereby declare that thefollowing is a full clear and exact description of the same referencebeing had to the accompanying drawings in which Figure 1is a generalview of the machine embodying our invention attached to car. Fig. 2is aside elevation of the same with draw heads coupled together showing thethree longitudinal sections of the same. Fig. 3-is a top view of themachine showing drawheads coupled together. Fig. 4is a view of themachine showing drawheads with top sections removed exhibiting top ofpin tripper Fig. 5 is a side view of shank and a longitudinal verticalsection of drawhead through pin tripper D. Fig. 6is a view of rear endof shank. Fig. 7is a rear view of draw head showing pivot pin 0. Fig.8-is a front view of drawhead showing coupling pin (h) held in positionby pin tripper D.

Similar letters refer to similar parts throughout the several views.

The objects of our invention are the coupling automatically anduncoupling of railway cars in a new and improved manner which we attainby the mechanism illustrated in the accompanying drawings which has anew and improved drawhead A (Fig. 1) of peculiar shape shown made ofthree longitudinal horizontal sections of suitable metal a, c, I),respectively representing the upper center and bottom sections andriveted together as shown in Figs. 1, 3 and 4E. The drawhead isconnected with the shank B by an ordinary hinge joint pivoted by a steelpin 0 to the shank B so as to allow for motion of cars in passing overcurves. In sections a, Z) and c, are circular openings for reception ofpin h, which pin h,

(Fig. l) is held in position by pin tripper D which has a verticalslotted hole 61 through which a steel pin f, is placed to guide the pintripper. The pin tripper also has an oblique base 6 which moves on aninclined plane in a cavity in the drawh'ead being guided by the pin inthe slotted opening up and down the inclined plane of the cavity in thedrawhead so that when the position of the drawhead strikes the pintripper it is forced up the inclined plane (g) guided by pin (f) andthus allows the coupling pin, \V, which it held in position (Fig. 1) tofall, pass through the circular openings for its reception and thussecurely and effectively and automatically couple the cars. There is alever rest attached to end of car (p) which supports the lever (it) whencoupled.

The coupling is effected by means of the steel pin (h) (Fig. 1) droppingas before described and passing through circular openings in eachdrawhead which fit into each other, one forming the counterpart of theother, a male and female part as shown in Figs. 3 and 4.

The uncoupling is effected by raising the pin (h) by means of anordinary shackle (j) attached to the pin 0 in an ordinary manner andmoving in a slot (10) in a new and improved lever (in) peculiarly shapedas shown in diagram and attached to an ordinary shaft or rod (L) on rearof car as shown in Fig. 1 of accompanying drawings.

The lever (K) is of the peculiar shape indicatedin drawingshaving intheouterextremity an elongated oval opening (K') with the greatestcurvature toward the extremity and having a particular convex lower partand a concave upper-part,the whole made of suitable metal. The shank Bis made of suitable metal in three longitudinal horizontal sections m nand 0 respectively the upper center and bottom, the center sect-ionhaving peculiar raised portions on its two outer and exposed sides whichdo not extend to the outer edge of the sections or and 0 as seen in Fig.4:. Te prefer the center section at to be made of cast iron with holesfor rivets through the enlarged portions thereof which thus affordsgreater strength and less bulk than if one continuous part equal indimensions with the top and the two sections m and which have circularopenings for pivot pin 0 the center section 7% forming at its extremityin head a butt for hinge as in Fig. 4. In the drawhead we prefer to havethe center section made of forged steel and the top and bottom sectionsmade of steel castings but the several parts of the whole mechanism maybe made of any suitable metal.

What we claim as our invention and desire to secure by Letters Patentis,

1. The combination in car-couplers of a drawhead A made in three partsa, b and c, and having its shank B, made in horizontal sections m, n, 0,a pin tripper D with oblique base 6, having a slotted opening d, a steelpin f, a coupling pin h, shackle j, attached to coupling pin h, lever ishaving slotted openingk, and pivot pin 0, substantially as hereinbeforedescribed and shown and for the purposes therein set forth.

2. The combination of a pin tripper D which has an oblique base and avertical slotted hole (d) through which a steel pin (f) is placed toguide it, with a drawhead having a cavity with an inclined plane, 9,upon which the oblique base of the pin tripper, e, moves up and downwhen pushed in by center section of the drawhead when cars are shuntedtogether the pin tripper holding the coupling pin in position ready todrop when cars are shunted together substantially as hereinbeforedescribed and for the purposes therein set forth.

3. The pin tripper D having an oblique base also slotted opening 01, anda steel pin f, passing through it as shown and described and for thepurposes set forth.

4. The lever is of the peculiar shape shown in the drawings and havingin its extremity a slotted opening 70 of the peculiar shape shown inwhich a shackle works for the purpose of lifting the coupling pins inposition substantially as and for the purposes hereinbeforeset forth anddescribed.

5. A shank 13 made of suitable metal in three longitudinal horizontalsections m, "rt, 0 respectively the upper center and bottom sections, asshown in drawings, substantially as hereinbefore described and for thepurposes therein set forth.

Dated at the city of Moncton, in the said county of Westmoreland, insaid Province of New Brunswick, this 8th day of April, A. D.
